Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. The term plastic is used herein e660 refer only to the time-independent that is, noncreep component of inelastic strain.
Next Checking to see if you are a returning visitor…. Also, both strains are typically used to establish cyclic limits and total strain usually is controlled throughout the cycle. In particular, cyclic total strain should be measured and cyclic plastic strain should be determined.
The presence of time-dependent inelastic strains during elevated temperature testing provides the opportunity to study the effects of these strains on fatigue life and on the cyclic stress-strain response of the material. Data analysis may not follow this test method in such cases.
The test method may be applied to hourglass specimens, see Fig.
Strain-controlled fatigue is a phenomenon that is influenced by the same variables that influence force-controlled fatigue. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are awtm within the subject standard but are not provided as part of the standard.
ASTM E606 Strain-Controlled High and Low Cycle Fatigue Testing
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. To truly determine a time-independent strain the force would have to be applied instantaneously, which is not possible.
Results of a low-cycle fatigue test program may be used in the formulation of empirical relationships between the cyclic variables of stress, total strain, d606 strain, and fatigue life. Testing is limited to strain-controlled cycling. Link to Active This link will always route to the current Active version of the standard. We are confident that we have what you are looking for.
Work Item s – proposed revisions of this standard. Information obtained from strain-controlled fatigue testing may be an important element in the establishment of design criteria to protect against component failure by fatigue.
ASTM E – 04 Standard Practice for Strain-Controlled Fatigue Testing
Information obtained from low-cycle fatigue testing may be an important element in the establishment of design criteria to protect against component failure by fatigue. Furthermore, either of these strains typically are used to establish cyclic limits; total strain usually is controlled throughout the cycle. This value should increase with increasing test temperature.
While f606 practice is intended primarily for strain-controlled fatigue testing, some sections may provide useful information for force-controlled or stress-controlled testing. It is intended as a guide for sstm fatigue testing performed in support e60 such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. When testing for strain-controlled fatigue, it can be noted that it is influenced by the same variables that influence force-controlled fatigue.
Although low-cycle fatigue is a phenomenon that is influenced by many of the same variables that influence high-cycle fatigue, the nature of low-cycle fatigue imposes distinctive requirements on fatigue testing methods. No restrictions are placed on environmental factors such as temperature, pressure, humidity, medium, and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are detailed in the e66 report.
Low-cycle fatigue can be an important consideration in the design of industrial products. Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint.

No restrictions are placed on environmental factors such as pressure, temperature, medium, humidity and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are explained in the final report.
The uniqueness of this test method and the results it yields are the determination of cyclic stresses and strains at any time during the tests. Active view current version of standard.
It is intended as a guide for fatigue testing performed in support of such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. Examination of the cyclic stress — strain curve and its comparison with monotonic stress — strain curves gives useful information regarding the cyclic stability of a material, for example, whether the values of hardness, yield strength, ultimate strength, strain-hardening exponent, and strength coefficient will increase, decrease, or remain unchanged that is, whether a material will harden, soften, or be stable because of cyclic plastic straining 1.
